Ask HN: Is clearing browser data (cookies, cache, history) enough?

I'd like to stop having to accept / reject every privacy pop up that shows up.

I have an idea:

1) Find (or build) a browser plugin that auto-accepts all GDPR and tracking pop-ups.

2) Set my browser to clear all data when I close the browser.

3) Always browse in Incognito mode.

I'm thinking of following the above steps instead of spending the time to Reject All tracking on each website I encounter.

I was wondering if you think my idea is dumb, incomplete, or something else.

Thank you!
